My objective here is really simple — I’m trying to set an NSString to some test data, then return the class, which should be NSString. Here’s my code:
NSString* stringer = [NSString stringWithFormat: @'Test']; NSLog(@'%@', [stringer class]); The log says that the class is NSCFString, not NSString. What’s going on here?
NSString is really a container class for different types of string objects. Generally an NSString constructor does return an object that is actually of type NSCFString, which is a thin wrapper around the Core Foundation CFString struct.
